3. PHOTOGRAMMETRIC EVALUATION
Phodis ST Stereo Evaluation software has been used at the
project. Phodis ST is software in the Zeiss PHODIS
Photogrammetric Digital Image System. This software is used
• To form the digital image based stereo models,
• To visualize the stereo models on the screen with 3D
floating mark,
• To draw the measurement results with stereo super
imposing using Phocus, Micro station and CadMap
software
The components of the system are the computer with Unix
System, stereo visualisation system and the special P mouse.
The source data are the digital images, camera information,
control points and the model set up information.
3.1 Forming The Stereo Models
In spite of the images are taken with terrestrial cameras, the
evaluation is performed using stereo evaluation software.
The evaluation has been done using developed soft wares
with stereo models because of the object being not a plane
surface and having different y distances. The 6cm*6cm
formatted images taken with terrestrial camera are scanned
with 14 micron pixels in tiff format and transferred to the
computer media.
4. APPLICATION
4.1 The Used Camera
Rolleiflex 6008 metric camera with Sonnar 4/150 mm-
objective Fig.3 is used to obtain the silhouette. The
calibration has been performed in 24.05.2002 in the factory
in Germany and the calibration results are delivered with a
protocol. According to this protocol the interior orientation
elements are as follows:
